Update design scaler component

See merge request gitlab-org/gitlab!46205

This commit is in light of the previous commit,
where GlButtonGroup is now used in the component.

As BitBucket importer tried to fetch all Pull Requests upfront, before
importing it, the memory consumption got very high. So high, that bigger
projects could never be imported fully, as they had too many Pull
Requests.

This change should reduce the amount of occupied memory, as the Pull
Requests are now fetched and imported in a batch of 100. As it used to
be done before hand, for creating pull request branches.

Use Helm 3 for GitLab-managed apps in new clusters [RUN AS-IF-FOSS]

See merge request gitlab-org/gitlab!46267

With this change, any existing cluster will continue to use
Helm 2, while all new clusters will use Helm 3 for GitLab-managed apps.
Note that this only applies to GitLab-managed apps -- Auto DevOps
uses its own Helm version on a per-project basis.

The diff looks big because we split the Helm command classes into two
modules, V2 and V3, to allow them to evolve independently as long as
they both implement the same minimal interface.

The command classes in the V2 module should be exactly equal to their
old counterparts, besides the addition of BaseCommand#helm_version,
which the common Kubernetes pod generator uses to resolve the container
image.

The command classes in the V3 module are ports of the relevant subset of
commands. There are more classes in the V2 module because we carried
along support for in-cluster Tiller. This is currently unused, but may
be used to clean up Tiller if we decide to offer Helm 2 to 3 migration
in the product later on.

Add reposition_note permission

See merge request gitlab-org/gitlab!45957

This works as an alias of `admin_note` unless the noteable is a Design,
in which case it will be true if the user can `create_note`.

This allows us to make a new mutation for repositioning a note on a
Design which will allow users who did not create the note to
reposition it.
